Ta all whom it may concern:

Be it known that I, FRANK Gunmen Stirr- TER, citizen of the United States of America,

residing at Buenos Aires, Republic of Ar-- gentina, have invented certain new and'useful Improvements in Transmission Belt Fasteners, of which the following is a specification.

This invention relates to certain improve ments in transmission belt fasteners its object being to provide a device of said nature specially designed to join the two ends of belts or transmission bands and which withstructed in a variety of sizesand'out of suitable materials, according to the object for which it is to be used.

This system of fastener presents the i fol- I lowing advantages over those now in use.

the joint becomes more solid by increased belt strain. p I

The fastener may be made from east or wrought metals in a single piece or made up fromv several pieces although preferably it. is stamped inone piece' frornsheet stock.

In order that my invention may be clearly understood and easily carried into practice a preferred embodiment of the same has been illustrated in the accompanying drawings, in which Figure 1 shows a perspective view of my improved fastener and the man.- ner in which the belt end is fixed to the same. Figure 2 isalongitudinal section of the said fastener with the belt-ends in position. Fig. 3 is a perspective View .of the fastener without the belt attached.

In the drawings a stamped metal frame is shown with edges, longitudinal to belt, bent downat right angles to topsurface to give stiffness and avoid unnecessary lateral projection.

c It will be seen that the fastener is curved 'longitudinallywith belt. This is ,done to" place the cross-bars 2 and 3 at a lower level than, the inside cross-bars 4 and 5 this securing a greater pressure at the point ofeontact between the active portion of the belt and the folded-over end (6 and 7) which becomes squeezed between the cross-bars 2 and 3 'and'the active portion of the belt; the squeezing increasing as the belt tightens.

Many structural and other changes, may

be introduced without departing from the scope of my present invention which has been clearly set forth in the appended claimin clauses.

aving now fully described and ascer tained the nature of my present invention and in'what manner the same is to be carried into practice, I declare thatwhat I claim and desire to-protect by my Letters Patent A belt coupler, embodying a substantially rectangular integral framecomprising outer and inner pairs of cross-bars, and overhangingfiange pieces connecting the ends thereof to strengthen the-same; the bars of each pair being spaced from each other and from the adjacent bars of the other pair, and the flange pieces projecting downwardly an appreciable distance below all of the bars,

whereby each end of the belt may be inserted, upwardly through the space between the inner pair'of bars and thenpassed back wardly across the outer face of the adjacent 1 inner bar and inserted through the space between the latter bar and the adjacent outer bar and finally passed outwardly be neath the last-named bar; the said flange pieces extending across the side edges of the folded portionsof the belt ends and the por tions of the belt ,to-which said folded poitions are immediately connected for pre venting lateral movement of the bell; ends,

In testimony whereof I alfix my signature' FRANK GEBRISH'SENTER.
